Multi-Chain Architecture vs Single Chain Focus + +**Chosen Approach**: Multi-chain with chain-specific adapters + +**Why**: Different blockchains require different metrics and APIs. Bitcoin uses UTXO model while Ethereum uses account-based model. A unified interface with chain-specific implementations provides flexibility while maintaining consistent output formats. + +**Alternatives Considered**: +- **Single Chain Only**: Rejected due to limited market coverage +- **Chain-Agnostic Generic Metrics**: Rejected due to loss of blockchain-specific insights +- **Separate Tools Per Chain**: Rejected due to code duplication and maintenance burden + +### 2. Data Source Strategy: APIs vs Full Node + +**Chosen Approach**: Hybrid API-based with optional full node support + +**Why**: Most users don't run full nodes. Using APIs (Etherscan, Blockchain.com, Glassnode) provides immediate access without infrastructure requirements. Full node support remains optional for advanced users needing maximum decentralization. + +**Alternatives Considered**: +- **Full Node Required**: Rejected due to high infrastructure costs ($500+/month) +- **APIs Only**: Considered but added full node option for enterprise users +- **Light Client Sync**: Rejected due to incomplete data and sync time requirements + +### 3. Whale Detection Threshold Method + +**Chosen Approach**: Dynamic percentile-based thresholds with absolute minimums + +**Why**: Static thresholds (e.g., "1000 BTC = whale") become outdated as prices change. Using percentile-based detection (top 0.1% holders) with absolute minimums (e.g., $1M USD equivalent) adapts to market conditions. + +**Alternatives Considered**: +- **Fixed Token Amounts**: Rejected due to price volatility making thresholds obsolete +- **USD Value Only**: Rejected as it misses on-chain concentration patterns +- **Machine Learning Clustering**: Rejected due to complexity vs accuracy tradeoff + +### 4. Data Storage: Time-Series Database vs Relational + +**Chosen Approach**: Time-series database (InfluxDB) for metrics, PostgreSQL for metadata + +**Why**: On-chain metrics are time-stamped numerical data perfect for time-series databases. InfluxDB provides efficient storage, fast queries, and built-in downsampling. PostgreSQL stores wallet metadata, labels, and relationships. + +**Alternatives Considered**: +- **PostgreSQL Only**: Rejected due to poor time-series query performance +- **InfluxDB Only**: Rejected due to poor relational data handling +- **ElasticSearch**: Rejected due to higher complexity and resource requirements + +### 5. Real-Time vs Batch Processing + +**Chosen Approach**: Hybrid batch + real-time for whale alerts + +**Why**: Most metrics update every 10-15 minutes (blockchain confirmation time). Batch processing handles historical data efficiently. Real-time processing monitors mempool for large transactions requiring immediate alerts. + +**Alternatives Considered**: +- **Batch Only**: Rejected due to delayed whale movement detection +- **Real-Time Only**: Rejected due to high API costs and rate limits +- **Streaming-First Architecture**: Rejected as overkill for blockchain data latency + +## Prerequisites + +### 1.

time-stamped metrics +- **Implement Rate Limiting**: Respect API limits with exponential backoff and request throttling +- **Cache Static Data**: Store exchange addresses, token metadata locally to reduce API calls +- **Validate All Addresses**: Use `Web3.is_address()` before making contract calls +- **Monitor API Costs**: Track API usage to avoid unexpected bills with premium providers +- **Store Historical Data**: Keep 90+ days of metrics for trend analysis and comparisons +- **Use Async Operations**: Async/await enables concurrent API calls without blocking +- **Label Wallet Addresses**: Maintain database of known exchanges, team wallets, contracts +- **Set Alert Thresholds**: Configure meaningful thresholds to avoid alert fatigue +- **Test with Testnets**: Validate logic on Goerli/Sepolia before mainnet deployment + +### DON'T + +- **Don't Query Full History**: APIs have limits; fetch incremental data and build locally +- **Don't Ignore Chain Reorgs**: Wait 12+ confirmations before marking data as final +- **Don't Hardcode API Keys**: Use environment variables and secret management +- **Don't Trust Single Data Source**: Cross-reference multiple APIs for critical decisions +- **Don't Skip Error Handling**: Network issues are common; implement robust retry logic +- **Don't Store Raw Blockchain Data**: Process and aggregate; full node data is terabytes +- **Don't Run Without Monitoring**: Set up alerting for analysis failures and anomalies +- **Don't Forget Decimal Precision**: Use `Decimal` type for financial calculations +- **Don't Neglect Compliance**: Some jurisdictions restrict blockchain data collection +- **Don't Over-Engineer**: Start simple; add complexity only when needed + +## Performance Considerations + +1. **API Rate Limits** + - Free Etherscan: 5 calls/second, 100k/day + - Infura Free: 100k requests/day + - Glassnode: Premium required for high-frequency data + +2. **Database Performance** + - InfluxDB: 1M+ points/second write capacity + - PostgreSQL: Index `address`, `timestamp` columns + - Use connection pooling for concurrent queries + +3. **Network Latency** + - Average API response: 100-500ms + - RPC node latency: 50-200ms + - Batch requests when possible to reduce round trips + +4. **Memory Usage** + - 10,000 holders = ~2MB memory + - 100 blocks of transactions = ~50MB + - Use streaming for large datasets + +5. **Optimization Strategies** + - Cache token metadata (supply, decimals) for 1 hour + - Aggregate metrics every 15 minutes, not per block + - Use database materialized views for complex queries + - Implement data downsampling for older metrics + +## Security Considerations + +1. **API Key Protection** + - Store in environment variables, never commit to git + - Use separate keys for development/production + - Rotate keys quarterly + +2. **Data Privacy** + - Blockchain data is public, but aggregated analysis may reveal patterns + - Don't store personal information linked to addresses + - Comply with GDPR if analyzing EU users + +3. **Input Validation** + - Validate all addresses before queries + - Sanitize user inputs to prevent injection + - Limit query ranges to prevent DoS + +4. **Rate Limiting** + - Implement application-level rate limiting + - Monitor for unusual query patterns + - Set maximum concurrent requests + +5. **Secure Communication** + - Use HTTPS for all API calls + - Verify SSL certificates + - Consider VPN for sensitive production deployments + +## Related Commands + +- `/track-price` - Real-time cryptocurrency price monitoring +-
